T 0 all 71:71 om'i't may concern:

-Be it known that I, PERRY F. LANDPHERE, a citizen of the United States,residing at Mazon, in the county of Grundy and State of Illinois, haveinvented a new and useful R0- tary Flow, of which thefollowing is aspecificationl This invention has relation to rotary plows and itconsists in the novel construction and arrangement of its parts ashereinafter shown and described.

The object of the invention isto provide a plow with a series of rotaryplowing members so mounted in the frame that t e plow is turned thepivotal point of the plow as an en tirety will occur at the edge of oneof the rotary members which is in contact with the ground therebyreducing the frictional contactof thesaid rotary mom-hers with the soilduring the act of turning the plow.

A further object of the invention. is to provide a plow of the characterindicated which is of s ecial and durable construction.

Int 1e accompanying dmwings: Figure 1 is a top plan view of the plow.Fig. 2 is a side elevation of the same. Fig. 3 is a sectional view ofthe rotaryplowing members, and Fig. 4 is an elevation of a levermechanism used for shifting the shaft upon which the rotarly plowmembers are mounted.

' he plow-consists of the rectangular frame 1 which is preferably squareor the frame may be circular.

The frame 1 is provided at opposite corner ortions with the parallelpieces 2 and 3 w iich are diagonally disposed with relation to theframe. The shaft .4 is j-ournaled at one end in the piece 2 and at itsopposite end is located in the elon ated opening 5 provided in the piece3. The link 6 is pivotally connected at one end with the shaft lever 7which is ul'crumed upon an upright 8 attached to the piece 3. Saidupright is provided with a gear segment 9 which is adapted to be engagedby the pawl 10 carried-by the lever 7. The hub 11 is mounted upon theshaft 4 and is divided along its length bye series of transversereductions 12 into sections a, b, and c. The spokes 13 are attached.-

to the said sections in.the vicinity of the ends thereof of greatertransverse dimensions.

The spokes upon each section converge at an angle toward each other andtoward the axis 3 of the shaft 4. That is to say, the said spokes do notoccupy the same lane at a rlght angle to the axis of the she is 4. The

! outer ends of each set of spokes 13 are con nected together by a rim1! and the said rim is substantially of concaved configuration whichconcavity is generally followed by the dispositionsof each set ofspokes. The rear end of the hub 11 is rounded as sit-.15 and bearsagainst the strip 2 The forward portion of the frame 1 is provided withan extension 1%; to "which is attached the lug 17. The draft animals arehitched to the iug 17. T he frame 1 is provided at its forwanl cornerswith the journal boxes 18 and 19 and at its rearsidc with a bracket 20which is provided with a journal l')o: :.21. The hearings in the saidboxes 18, 1'sand 21 are vertically. disposed and the s iindle shanks 22,23 and 24 are journaled in t e said boxes rcspecti cly. The groundwheels 25, 26 am L? are journaled upon the spindles of the'seidrespective shanks. A hood 28 is journalcd upon the upper end of each ofthe shanks'ZIZ. '33 and 2t and a lei er 29 is fulcrumcd to each. hoodand is provided with 5. pawl 30 udr'iptei'l to engage a gear seg ment 31also mounted upon t e need. A link 32 connects the working end of-thelevers 29 with the frame 1 or an extension thereof. By means of the saidlevers 29 the front or rear portions of the frame 1 may be raisedorlowered or either of the forward corners of thesaid frame may berelatively raised or lowered. The seat 33 is mounted upon the forwardportion of the frame 1 and the power ends of the forward levers 29 arewithin convenient reach of one who occupies the said seat. The arm 34 isfixed to the shank 22 and the arm 35 is fixed to the shank 23. Theconnecting rod 36 is pivotally at;- tached at its ends to the said arms.The guiding tongue 37 is fixed at its rear end to the shank 22. The arm38 is fixed to the shank 23 and is disposed substantially at arightangle to the arm 35. The arm 39 is fired to the shank 24 and-theconnecting rod 40 is pivotally attached at its ends to the arms 38 and39.

The shaft 4 is diagonally dis osed with relotion-to the frame 1 and thefdwest portion ;of the rim 14 of the intermediate rotary plowing memberis normally-located at a point below the center of the frame 1. It

to gue 37 is swunghorizontally that the w ieels 25 and 26 will be turnedin parallel relation while the wheel 27 will be turned in an oppositedirection. This is due to. the

will therefore be seen that when the guiding the arm. lies u outheopposite shank from t rut side in which the arm 58 extends from theshank 23. Thus during the act of turning the'f raine l is swung aroundupon a point occurring substantially at its center and as the lowestpart of the rim '14: of the intermediate plowing member located inVertical alinenient with this pol L the turning of the plow is VirtuallyKliCUlrlPliSlllkl upon the lowest point of the rim ll of theintermediate plowing member as a pivot, This peculiar relation of thelowing members with the ground wheels 1 4-K. icduves we winters l t sjih1hr:- soii during the act of turning the t.

In testimony that I claim the foregoing'as my own, I have hereto afiixedmy signature in the presence, of two witnesses.
